What is the use of Trusted system? I know that there is no need of UID and PWD to communicate with partner system. In what situation it is good to go for Trusted system?
E.g. if you have an R/3 system and a BW system and don't want to maintain passwords. Same goes for CRM and a lot of other systems/applications.
Let me know if my understanding below is correct:
1) By default the RFC destination is synchronous
2) Asynchronous RFC is used in case if the system initiated the RFC call no need to wait for the response before it proceeds to something else.
Yes - that's right.
But keep in mind that it's not only a technical issue whether to switch to asynchronous. The application must also be able to handle that correctly.

How to see when were the optimizer stats last time run? We are using win2k, oracle 9, sapr346c.
Assumed DB=Oracle. Select any table let’s take MARA here but you should do the same for MSEG and few others to see whether the dates match or not. Run the following command on the command prompt:-
select last_analyzed from dba_tables where table_name like '%MARA%';
This gives you a straight answer .Else you can always fish around in DB14 for seeing when the optimzer stats were updated.
